Restricted-user privilege escalation via unchecked endpoints
Published Jul 12, 2022 · Updated Apr 7, 2026
Authentication and authorization flaws in Novastar Novaicare 7.16.0 allow remote authenticated users to gain privileges through web endpoints. Backend handlers for enterprise information, SMTP settings, roles, and user deletion fail to enforce the requesting account's restricted role, exposing data and destructive administration actions. Exploitation requires a valid low-privilege account; the vendor reports that the legacy endpoints were decommissioned in April 2026.
